What is 'craft' beer? Formalistically speaking.

The [U.S.] Brewers Association —the trade association which bills itself as "the not-for-profit trade group dedicated to promoting and protecting America’s small and independent craft brewers"— has 'kicked out' several member breweries when they no longer comported with the association's (changing) definition of what a craft brewery was.

Currently, the BA holds that ...

an American craft brewer is small, independent, and traditional.

Small:
Annual production of 6 million barrels of beer or less (approximately 3 percent of U.S. annual sales). Beer production is attributed to the rules of alternating proprietorships.

Independent:
Less than 25 percent of the craft brewery is owned or controlled (or equivalent economic interest) by a beverage alcohol industry member that is not itself a craft brewer.

Traditional:
A brewer that has a majority of its total beverage alcohol volume in beers whose flavor derives from traditional or innovative brewing ingredients [emphasis mine] and their fermentation. Flavored malt beverages (FMBs) are not considered beers.

It's that definition of 'independent' that, in May, the BA employed to knock-out Lagunitas and Wicked Weed. Notwithstanding —at Thinking Man Tavern, in Decatur, Georgia, on 13 July 2017— both beers, née 'craft,' still went down damn tasty.
